Bad alternator or belt tensioner?
Have had this sound for a couple months now it started right after I changed my spark plugs, car drives great still but I literally can’t figure it out, the closest things I can find are alternator or supercharger belt tensioner, I’ve tried seeing if it was my ac but it’s their regardless if ac is on. Please any advice?
